fratress 

A girl that hooks up with Frat Guys all the time. Like a mattress, she spends every night under a frat boy.

I was the first one to put a stain on that Fratress. --Nooch

frattress 

Young college female, often times a member of a sorority, who spends an excessive amount of time having sex with brothers of a fraternity.

the term derives from fraternity + mattress, because the slut spends so much time under brothers that she might as well be their bed.

"Bro, you see that frattress over there? Yeah, the one on top of the table. I'm gonna do work and put her to use tonight."

"So, I was banging this frattress the other night, and after we got done she told me not to tell any of my brothers. You know she's just gonna tell those other sorostitutes how awful of a guy I am."

Fartress

An insult toward Fortress castle types in Heroes of Might and Magic III.

I don’t know why Ben is always Fartress, it’s such a stupid-ass weak town with awful level 6 and 7 creatures. The next time I take over one of Ben’s fartresses I’ll command my invading hero to take a shit in his Hydra Pond.
